Abstract: PLEASE NOTE THAT A MORE RECENT EDITION OF THIS TITLE IS AVAILABLE IN THE LIBRARYThe stomach functions as a reservoir that controls the size and rate of passage of ingesta into the small intestine, and initiates the digestion of protein and fat, and the absorption of vitamins and minerals. The stomach is made up of four functional regions: the cardia, fundus, body and antrum. The fundus and body expand to accommodate ingesta. The antrum is thick and muscular and grinds food into small particles that are triturated into the duodenum. The pyloric sphincter controls efflux into the duodenum, and the lower oesophageal sphincter prevents reflux of ingesta into the oesophagus. This chapter looks into Structure and function; Diagnostic approach; Evaluating gastric function; and Diseases of the stomach.
